Yeah, he's really good ae delving deep into the psyches of his characters even when they're morally in the wrong. I like to think the main difference between Cornelius and Billy is Mr. Snow worked his way to the top and had all the power in the world, but due to his nature made all the wrong choices, and Billy I like to imagine was a good kid who had no choice. Though his acting (Blyth) make you think about the psychology behind his characters. Makes you think. There's a huge difference between an EXCUSE and a REASON. Neither character has a valid excuse for their actions, like you can't say oh it's okay, I forgive him for everything he did, but everyone, even the most heinous of real life criminals, has a REASON. an excuse and a reason are different. An excuse is like a free pass, but a reason doesn't mean it's forgivable. Good acting makes you really think about that. Tom Blyth studied psychology as a minor you know. It shows man. Really thought provoking stuff.
